【摘要】 在室外用约 1 6m3水槽以止水方式进行了褶纹冠蚌滤水效果实验。结果表明 ,贝类滤水对水透明度影响明显 ,实验 4日后透明度由 2 1cm增加到 47cm ;对浮游生物量影响很大 ,每日生物量呈直线下降趋势 ;褶纹冠蚌的滤水率为 1 848～ 2 35 7Lg- 1 h- 1 。立体摆放组与平面摆放组之间的差别不明显 ,其差异尚待进一步研究。更多还原

【Abstract】 The filter function of Cristaria plicata Leach was studied in open air tanks of 16m3 during July of 2004.The results indicated that mussel filter had great effects on the transparency of water column,changed from 21cm to 47cm in 4 days.The amount of phytoplankton in the tanks reduced rapidly,performed linear decline by days.The filter rate of Cristaria plicata Leach was about 1.848～2.357Lg -1h -1.And there was no difference between between two methods of fixed and suspended mussles.How to make use of mussles filter function would be studied in future.更多还原
